Nvidia set to become first US chipmaker valued at over $1 trillion

AI took center stage after Nvidia stunned investors with a revenue forecast last week that surpassed analysts' expectations by more than 50%.

Nvidia Corp is close to breaching $1 trillion in market capitalization, making it the first U.S. chipmaker to join the trillion-dollar club.

The gaming and AI chip company, whose shares rose 3.8% in trading before the bell on Tuesday, was valued at $998 billion.

Meta Platforms Inc , valued at about $670 billion as of last close, clinched the trillion-dollar market capitalization milestone in 2021, while Apple Inc, Alphabet Inc, Microsoft Corp and Amazon.com Inc are the other U.S. companies that are part of the club.

Wall Street analysts called Nvidia's forecast "unfathomable" and "cosmological", hiking their price targets in droves. The highest price target valued the company at about $1.6 trillion, on par with Google-parent Alphabet.

"Given the valuation is well above the long-term average, there will be significant pressure to deliver high growth on a consistent basis ... there could be volatility in its share price to come," Susannah Streeter, head of money and markets at Hargreaves Lansdown, said.

Nvidia's shares rose about 25% last week sparking a rally in AI-related stocks and boosted other chipmakers, helping the Philadelphia SE Semiconductor index close on Friday at its highest in over a year.
